Specification of Letters Patent.

Patented Oct. 1, 1907.

To all whom it may concern:

Be it known that I, SOLOMON W. LERCI-I, a citizen of the United States,residing at Manasquan, in the county of Monmouth and State of NewJersey, have invented certain new and useful Improvements in Curbing, ofwhich the following is a specification.

My invention relates to improvements in curbing, and refers moreparticularly to a curbing made of artificial stone blocks, molded intothe desired form from concrete or other materials; and the object of myinvention is the provision of a simple and substantial form of curbinghaving a broad supporting base to provide a good solid foundation toprevent the curbing from being forced outward by the pressure'from thesidewalk.

Another object of my invention is to provide satisfactory means forbonding the curb blocks together so as to keep the curbing in properalinement.

With these and other objects in view, my invention consists of a curbingcomposed of blocks having an angular foot at the base thereof to providea broad foundation, and also of means for bonding the meeting ends ofthe blocks together; and the invention further embraces certain othernovel features of construction and combination of parts substantially asherein disclosed and as illustrated in the accompanying drawings, inwhich:

Figure 1, is a perspective view of two of my improved curbing units,showing the manner in which the ends are bonded. Fig. 2, is a crosssectional view of the curbing showing its relation to the sidewalk andstreet. Fig. 3, is a top plan view of the corner construction of thecurbing. Fig. 4, is a perspective view of a modified form of segment orcorner block. Fig. 5, is a detail view of a modified form of bondingconnection. Fig. 6, is a transverse sectional view of a modified form ofthe curb having depressions formed in the walls thereof so as to securea firm anchorage when set in position. Fig. 7, is a similar view ofanother modification in which the block is formed with a shoulder in theupper edge thereof to receive the edge of a flagstone or similarpavement.

The blocks or units constituting the curbing are preferably formed ofplastic concrete material molded, and each block is formed with anup-standing or retaining wall portion 1, adapted to form an abutment andsupport to the sidewalk material 2, as shown in Fig. 2, and the blocksare further provided with an out-standing angular foot or foundation '3,this foundation portion being generally covered by the pavement material4, the general location and arrangement of the street, sidewalk andcurbing being illustrated in Fig. 2. The angular foot forms a brace toprevent the upper portion of the curb from being forced outward, and thepaving material engaging the upper convex face 5, of the foot, securelyanchors the curb block in place.

To prevent longitudinal displacement of the adjoining ends of theblocks, bonding grooves 6, are molded in the ends of the blocks whichextend nearly to the lower edge thereof. These grooves are preferablysemi-circular or V in shape so as to form a complete circular or angularopening when the blocks are assembled, which opening is filled withmortar or a suitable key as indicated at 7. These bonding openings maybe long or short to suit different conditions, the two differentconditions being shown in Figs. 1 and 4. Openings 8, may be formed inthe wall of the curb block to afford holds to facilitate the handling ofthe same.

The corners of the curbing are formed by the curved segment blocks 9,these blocks being of any suitable radius, or if so desired, thestraight curb blocks are formed with a curved extension on the endthereof, this idea being shown in Fig. 4.

I11 order to more firmly anchor the blocks in place, grooves or channels11, may be formed longitudinally in the base and inner wall of theblock, which grooves form a bonding connection with the filling materialof the sidewalk and street pavement.

In order to form a neat and close joint between the fiagstones orsidewalk proper, the inner upper edge of the curb may be shouldered asat 12 in Fig. 7, to receive the edge of the flagstone 14. I

From the foregoing description taken in connection with the drawings,the many advantages and general usefulness and serviceability of mycurbing will be readily apparent and it will be further evident that Ihave accomplished all the results herein set forth as the I claim:

1. A curb block having an upstanding retaining wall portion and anangular foot extension disposed at right angles to the body of theblock, half round vertical bonding grooves in the ends of the block, andhand hold openings formed in the face of the block.

2. A curl) block comprising a flat base portion and a retaining wallportion at one edge .thereof upstanding at right angles therefrom,thebase and wall provided with recesses therein to form bondingconnection with the tilling material of the street and curl).

3. A curb block comprising a fiat base portion and a retaining wallportion upstanding from one edge thereof, the base and wall providedwith recesses therein to form bonding connection with the material ofthe street and curb, the ends of the block provided with verticalbonding grooves and the face of the block having hand held openingstherein.

In testimony whereof I aflix my signature in presence of two witnesses.
